LinearLayout in a ListView

So I'm trying to put a LinearLayout that has two TextViews inside of a ListView but I'm having trouble and the program keeps crashing with what I've tried. The ListView would just have one element. The xml for my Linear Layout is as follows: 

<ListView>
<LinearLayout
    android:orientation="vertical" 
    android:layout_height="wrap_content" 
    android:layout_width="fill_parent"
    android:minHeight="?android:attr/listPreferredItemHeight"
    android:gravity="center_vertical"
    android:drawablePadding="14dip"
    android:paddingLeft="15dip"
    android:paddingRight="15dip">
        <TextView 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"/>
        <TextView 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceSmall"/>
</LinearLayout>
</ListView>

How do I get this inside of a listview? When I try putting it in a listview, I get an error on the phone saying Sorry! The application has stopped unexpectedly. Please try again. The stacktrace is below.

You can try this

  final View layout = getLayoutInflater().inflate(R.layout.add_layout, null, false);
              TextView vr_name = lLayout.findViewById(R.id.name);
              vr_name.setText(v_name);
              linearListView.addView(layout);

I assume you are trying to customize the list items. You should write your own custom adapter to do that. Try this tutorial or you can check out these videos:

  1. Presenting your data in a ListView
  2. Transitioning to ListActivity
  3. Beautify your List: Get it working
  4. Beautify your List: Rigth way to do it

You have to use the ListView with a ListAdatper.

Create a class that implements ListAdapter, once of the method that you need to implement is:

public abstract View getView (int position, View convertView, ViewGroup parent);

With that method you will return a view for each of the elements of your list, and specify the layout that you want.

Also you should remember to reuse those views. For more information about how to use properly ListViews and ListAdapters:

http://dl.google.com/googleio/2010/android-world-of-listview-android.pdf

or the video

Cheers, Francisco.

That error is painful for my eyes to decipher to be honest. but normally you should be able to create a listview with one child element.

what I'm saying is:

<ListView>
 <LinLayout>
  <TextView/>
  <TextView/>
 </LinLayout>
</ListView>

this should work, since ListView only allows one child. But your LinearLayout can have as many as you want. If there's an error, it might be your layoutinflater.
